People didn't care about the evironment and they didn't protect it years ago. Some of the tourists threw the rubbish and plastic bags everywhere. People hunt and killed animals and caught birds. They stepped on the grass and flowers. And they cooked meals in the forests which sometimes lead to a forest fire.
Things are different now. More and more people pay more attention to the envionment. They don't litter and they bring the rubbish to the dustbins. People give up hunting and they take care of the animals and protect the grass and flowers. When they go hiking, they bring food with them and they don't cook in the forests.

Several years ago, man doesn’t know how to protect the environment, but now, this condition is greatly improved. Few travelers left the garbage behind in the past, but they will take away their garbage now. Man killed animals and caught the birds in the past, but now, they wouldn’t hunt for animals any more. Several years ago, they damaged the plant, but now, they protect it. Several years ago, they cooked in the forest, but now, they take made-up food in case of a forest fire.
Protect environment(环境保护)
The earth scale change of climate has brought a new kind of natural disaster and the developed and complicated city system is holding a latent risk of expanding the damage artificially. Also people has been spoiling the health since the immense quantity of chemicals have been produced and already used in pursuit of convenience and various toxic substances have been produced unintentionally and accumulated in environment. Therefore, We need some countermeasures from the viewpoint to prevent the city environment form disaster and to manage environmental risks. So we will develop and improve a new risk management system and a disaster prevention system to preserve and create the city environment where people feel easy and sound in their life.
Ago people didn't protect enviranment
